Spectralock

A Screen Reveal Technology

A word, phrase or simple graphic or logo hidden within a VariMatrix™ image is revealed by orienting a printed transparent screen on the surface of the hologram. SpectraLock™ is particularly interesting for certain applications as it does not require special lenses for decoding the hidden images. The decoder screens can be printed on flexible pieces of film so they are inexpensive as well as suitable for curved substrates.
